Well, on my website, at http://digilander.libero.it/foto_ras/Pressman_120.htm, I try to find a solution on "how can I use a 23 Graphic roll film holder on a Busch Pressman 4x5 ?". It works. Maybe it can help someone.
Sorry, it's in italian, but with a lot of pics.
Comments and suggestions will be higly appreciated.
TIA. Roberto.
